RE: Weaver - early prairie research

Here's a link to another paper, "Invasive Plant Suppresses the Growth of
Native Tree Seedlings by Disrupting Belowground Mutualisms":

John,

Steve Vaughn a Weedologist at the Northern Regional Labs, USDA, in
Peoria 
identified allelopathy in Garlic Mustard and wrote a paper on it. I
believe 
it can be accessed from the web but I don't know how.
Steve's work phone number is 309/ 681-6344.
Email: vaughnsf@ncaur.usda.gov

Good luck. I hope Steve doesn't kill me for putting out this info.

t the recent North American Prairie Conference I picked up
